Question

Which of the following units is/are the unit(s) of pressure? (I) Ns (II) Nm (III) N/m² (IV) J/m³ (V) J/kg
Options
A I
B III
C III and IV
Correct Answer
D V
Correct Answer

Option C is the correct answer.

Detailed Explanation

Pressure = Force/Area, so N/m² (Pascal) is unit. Also energy/volume (J/m³) has same dimensions as pressure. Ns is impulse, Nm is work/energy, J/kg is specific energy.

Hint

Pressure = force/area = energy/volume.
